Good but buggy
This game is tough but buggy
I made it to lvl 14 but just couldnt take the 6 silver tanks down fast enough, what doesnt help at all is the bugged normal tanks that i cant finish off with the machine gun and have to waste a cannon shot on
also i got a triple cannon which just hits a wider range then for more
I suggest let the normal tanks die by machine gun and increase the dmg of the cannon since my triple machine gun does far more damage.
As for how to play this ignore 2x dmg, and i did upgrade machine gun, upgrade cannon, upgrade reload, upgrade machine gun, upgrade reload upgrade cannon, upgrade machine gun then you'll hit lvl 10 by now so your forced to spend all your points on +100 hp since those silver tanks are tough as nails :(
Another problem is that you need the quad machine gun to kill helicopters, double / triple machine gun cant "finish" it off.
All weapons can hurt but cant deal the killing blow.
Actaully i would say upgrade machine gun twice, upgrade cannon upgrade machine gun, upgrade reload, upgrade machine gun, upgrade reload x2 / 3 until your forced to heal since the sivler tanks are TOUGH!
Good luck ^^
and please fix these immortal helicopters/ tanks :p also down grade the silver tanks a bit about -20% hp should make this game more doable
Also i got 3rd with 23k score :P \o/ i think the top2 were beta testers aka you or one of ur friends
